The History of the Telephone
STUDENT VERSION THE HISTORY OF THE TELEPHONE Activity Items There are no separate items for this activity. Student Learning Objectives • I will be able to name who invented the telephone and say why that invention is important. • I will be able to explain how phones have changed over time. THE HISTORY OF THE TELEPHONE STUDENT VERSION NAME: DATE: The telephone is one of the most important inventions. It lets people talk to each other at the same time across long distances, changing the way we communicate today. Alexander Graham Bell, the inventor of the telephone CENSUS.GOV/SCHOOLS HISTORY | PAGE 1 THE HISTORY OF THE TELEPHONE STUDENT VERSION 1. Like many inventions, the telephone was likely thought of many years before it was invented, and by many people. But it wasn’t until 1876 when a man named Alexander Graham Bell, pictured on the previous page, patented the telephone and was allowed to start selling it. Can you guess what “patented” means? CENSUS.GOV/SCHOOLS HISTORY | PAGE 2 THE HISTORY OF THE TELEPHONE STUDENT VERSION 2. The picture below, from over 100 years ago, shows Alexander Graham Bell using one of his first telephones to make a call from New York to Chicago. Alexander Graham Bell making a telephone call from New York to Chicago in 1892 Why do you think it was important that someone in New York could use the telephone to talk to someone in Chicago?

The History of the Telephone
THE HISTORY OF THE TELEPHONE BY HERBERT N. CASSON First edition A. C. McClurg & Co. Chicago Published: 1910 PREFACE Thirty-five short years, and presto! the newborn art of telephony is fullgrown. Three million telephones are now scattered abroad in foreign countries, and seven millions are massed here, in the land of its birth. So entirely has the telephone outgrown the ridicule with which, as many people can well remember, it was first received, that it is now in most places taken for granted, as though it were a part of the natural phenomena of this planet. It has so marvelously extended the facilities of conversation--that "art in which a man has all mankind for competitors"--that it is now an indispensable help to whoever would live the convenient life. The disadvantage of being deaf and dumb to all absent persons, which was universal in pre-telephonic days, has now happily been overcome; and I hope that this story of how and by whom it was done will be a welcome addition to American libraries. It is such a story as the telephone itself might tell, if it could speak with a voice of its own. It is not technical. It is not statistical. It is not exhaustive. It is so brief, in fact, that a second volume could readily be made by describing the careers of telephone leaders whose names I find have been omitted unintentionally from this book--such indispensable men, for instance, as William R. Driver, who has signed more telephone cheques and larger ones than any other man; Geo. -

A History of Audio Effects
applied sciences Review A History of Audio Effects Thomas Wilmering 1,∗ , David Moffat 2 , Alessia Milo 1 and Mark B. Sandler 1 1 Centre for Digital Music, Queen Mary University of London, London E1 4NS, UK; [email protected] (A.M.); [email protected] (M.B.S.) 2 Interdisciplinary Centre for Computer Music Research, University of Plymouth, Plymouth PL4 8AA, UK; [email protected] * Correspondence: [email protected] Received: 16 December 2019; Accepted: 13 January 2020; Published: 22 January 2020 Abstract: Audio effects are an essential tool that the field of music production relies upon. The ability to intentionally manipulate and modify a piece of sound has opened up considerable opportunities for music making. The evolution of technology has often driven new audio tools and effects, from early architectural acoustics through electromechanical and electronic devices to the digitisation of music production studios. Throughout time, music has constantly borrowed ideas and technological advancements from all other fields and contributed back to the innovative technology. This is defined as transsectorial innovation and fundamentally underpins the technological developments of audio effects. The development and evolution of audio effect technology is discussed, highlighting major technical breakthroughs and the impact of available audio effects. Keywords: audio effects; history; transsectorial innovation; technology; audio processing; music production 1. Introduction In this article, we describe the history of audio effects with regards to musical composition (music performance and production). We define audio effects as the controlled transformation of a sound typically based on some control parameters. As such, the term sound transformation can be considered synonymous with audio effect. -

Lawyers, Patents, and the Judgments of History CHRISTOPHERBEAUCHAMP Who invented the telephone? In the United States, this question has a widely known answer. Alexander Graham Bell routinely ranks among the hundred “greatest” or “most influential” Americans, whether chosen by historians or internet polls.1 His cry of “Mr. Watson—come here—I want to see you,”al- though often misquoted, is one of the best-known exclamations in Amer- ican history.2 More than one hundred and thirty years after the event, Bell and Watson’s first telephone call remains a classroom staple: a standard de- vice for teaching Americans about the nation’s inventive past, and even for placing technological change at the center of mainstream history.3 Christopher Beauchamp is the Sharswood Fellow in Law and History at the University of Pennsylvania Law School.

Media Technology and Society
MEDIA TECHNOLOGY AND SOCIETY Media Technology and Society offers a comprehensive account of the history of communications technologies, from the telegraph to the Internet. Winston argues that the development of new media, from the telephone to computers, satellite, camcorders and CD-ROM, is the product of a constant play-off between social necessity and suppression: the unwritten ‘law’ by which new technologies are introduced into society. Winston’s fascinating account challenges the concept of a ‘revolution’ in communications technology by highlighting the long histories of such developments. The fax was introduced in 1847. The idea of television was patented in 1884. Digitalisation was demonstrated in 1938. Even the concept of the ‘web’ dates back to 1945. Winston examines why some prototypes are abandoned, and why many ‘inventions’ are created simultaneously by innovators unaware of each other’s existence, and shows how new industries develop around these inventions, providing media products for a mass audience. Challenging the popular myth of a present-day ‘Information Revolution’, Media Technology and Society is essential reading for anyone interested in the social impact of technological change. Brian Winston is Head of the School of Communication, Design and Media at the University of Westminster. He has been Dean of the College of Communications at the Pennsylvania State University, Chair of Cinema Studies at New York University and Founding Research Director of the Glasgow University Media Group. His books include Claiming the Real (1995). As a television professional, he has worked on World in Action and has an Emmy for documentary script-writing.

Telephone – Inventions That Revolutionized the World
Telephone – Inventions that Revolutionized the World December 14, 2018 First Publication Date: 27th November 2010 The most common devices used for transmitting the voice signal over a greater distance are pipes and other physical mechanical media. All of us as a child must have used this form for communication. Another device used for centuries for voice communication is lover’s phone or tin can telephone. The classic example is the children’s toy made by connecting the bottoms of two paper cups, metal cans, or plastic bottles with string. But the invention which changed the entire scenario of the communication is the telephone. It revolutionized the entire communication system. People could hear the voice of their loved ones staying miles away. Telephone comes from the Greek word tele, meaning from afar, and phone, meaning voice or voiced sound. Generally, a telephone is any device which conveys sound over a distance During the second half of the 19th century many well-known inventors were trying to develop an acoustic telegraphy for economic telegraph messages which included Charles Bourseul, Thomas Edison, Antonio Meucci, Johann Philipp Reis, Elisha Gray, and Alexander Graham Bell. The ‘speaking telegraph’ or in simple terms ‘telephone’ emerged from the creation and gradual improvement of telegraph. The invention of telephone has been one of the most disputed facts of all time. Credit for the invention of the electric telephone is never an ending dispute and new controversies over the issue keeps arising from time-to-time. The Elisha Gray and Alexander Bell controversy raises the question of whether Bell and Gray invented the telephone independently and, if that’s not true, then whether Bell stole the invention from Gray. -
